In this paper we are studing the diet composition of the short-toed treecreeper's Certhia
brachydactyla (Brehm, 1820) nestling in the suburban area of El Harrach (Algeria).
Fluctuating asymmetry as a biomarker of habitat fragmentation in an area-sensitive passerine, the Eurasian treecreeper (Certhia

americana, especies que se limitan a areas extensas de bosques maduros, densos y con abundancia de arboles muertos en pie (Collar, 2001; Harrap, 2008).
Edge effect and matrix influence on the nest survival of an old forest specialist, the brown creeper (Certhia
familiaris, Oriolus oriolus, Nucifraga caryocatactes, Pyrrhula pyrrhula, and Coccothraustes coccothraustes were classified as woodland species.
During the fall migration, the White-throated Sparrow (n = 32), Nashville Warbler (n = 14, Oreothlypis ruficapilla), Swamp Sparrow (n = 14, Melospiza georgiana), and Brown Creeper (n = 14, Certhia
americana) were the most frequently observed fatalities.
